T @ZZ 1.072.072?, it may concern.:

Be it known that I, CHARLES E. PARKS, a

. citizen of the United States, and a resident of 'Watertowin in thecounty of Jefferson, and in the State of lVisconsin,have inventedcertain new and useful Improvements in Looms for leaving Slat-and-VireFabrics; and I do hereby declare that-the following; is a full, clear,and exact description thereof.

My invention consists in certain peculiarities of construction andcombination of parts, to be hereinafter described with reference to theaccompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a front elevation of my loom,having portions thereof broken away and in section for the purpose ofbetter illustration; Fig. 2, a top plan view partly in horizontalsection; Fig. 3, a section on line 3 3 of Fig. l; Figs. l and 5, detailsections respectively taken on lines 4 4 and 5 5 of Fig. 3; Fig. 6, adetail plan view of a gripping device employed in said loom; Fig. 7,adetail View illustrating the crossing of Wires that form the warp of thefabric produced by the aforesaid loom; Fig. 8, a detail plan view,partly in section, on line S 8 of Fig. 9, illustrating, an automaticfeed mechanism for the slats that form the filling of said fabric; Fig.9, a section on line 9 9 of the preceding ligure; Fig. 10, a detail endView of the slat-feed; Fig. 11, a section on line 11 1l of Fig. 10, andFig. 12 a detail elevation of a portion of the slat receiver andcarrier.

Referring by letter to the drawings, A represents supports for the frameB of the loom, and the upper and lower sides of this frame are slotted,as shown at l), to receive the ends c of the inner side C of a slatcarrier. Plates d, arranged at certain intervals t0 leave interstices c,connect the inner and outer sides C D of the carrier, and secured tothese sides of said carrier are blocks f, in register with the platesand at the same intervals apart, the opposing faces of these blocksbeing cut away on a bevel, so as to present less surface to slats fedinto the receiver and carrier through an opening gin the upper side ofthe loom-frame. The ends c of the inner side C of the receiver andcarrier are connected by pitmen E with cranks h on a shaft F, that hasits'bearings t' on the upper and lower sides of the loom-frame, saidshaft being provided,

with a bevel gear-wheelj, in mesh with a pinion 7s on another shaft G,arranged in bearings m on a brace-beam H and rear end of the loom-frame.

Loosely arranged on the shaft G is a driving-pulley I, having its hubprovided with one section n of a clutch, the other section 0 of thisclutch being splined on said shaft and suitably connected to a slide-rodJ, the latter being joined to a lever K, as best illustrated in dottedlines in Fig. 1, wherebythe latter clutch-section may be thrown in andout of engagement with the one on the driving-pulley to start and stopthe operation of the loom. l The lower side of the loom-frame isrecessed opposite the opening g in the upper side thereof to receive thesocket end p of a plate L, and when a slat is fed to the receiver andcarrier it drops into the socket and is thus properly positioned priorto the forward travel ot' said receiver and carrier, the socket portionof the plate being curved, as shown in Fig. 1, to permit of the slathaving an easy rise out of said socket when the aforesaid receiver andcarrier is actuated.

Connected to cross-braces M of the loomframe are spring-fingers N,arranged to come on opposite sides of the fabric produced by the loom,and the rear ends of the lingers are preferably serrated, so as toobtain a better grip on each slat that is beat up in the shed formed bythe warp-wires as the operation of weaving the fabric takes places.Hereinafter the fingers N will be termed grippers, and attention iscalled to the fact that the serrations thereon are so arranged as toresist rearward movement of the fabric without interfering with theforward movement ofl the,

Sule.

Journaled in forward extensions q q of the y loom-frame receives a reelQ, that turns there with, and the forward extension q of the upper sideof said loom-frame is hinged, so as to be laid back in order that thereel may'be slipped on and off said shaft.

Jonrnaled in the upper and lower sides of the loom-frame, in rear of theslat receiver and carrier, are parallel shafts R R', provided withcrosser or spreader arms r, as best illustrated in Fig. 4.-. Theseshafts are connected by gear-wheels s s', and the shaft R is providedwith another gear-wheel t, that meshes with a pinion u on the shaft F,above described. A pulley S is fast on the spreadershaft R', and a beltT connects this pulley with the one P on the reel-shaft O, as shown infull and dotted lines in Fig. 3.

In rear of the crosser-shafts the upper and lower sides of theloom-frame are provided with brackets U, set at au angle to a horizontalline and provided with bearings for grooved rollers V V', thisconstruction and arrangement of parts serving as a means to cause thewarp-wires of the fabric to draw evenly from spools W, loosely arrangedon spindles X, that project from a wall Y at the rear of the loom-frame.Each spool-spindle has an ontturned tiange n at its inner end forimpingement against the adjacent head of a spool, and the outer end ofeach spindle is squared to receive a collar w, that is held against theother spool-head by means of a spiral spring at, adjustable as totension on the stem of a screw y, that has its bearing in said squaredend of the spindle. By the means just described the spools are tensionedby their frictional contact with the flanges n and collars w on thespindles, whereby the wire on said spools is not unwound any faster thanis necessary.

Arranged in front of the cross-braces M is a pressure-roller Z, thatbears against the fabric and guides the same to the reel, the positionof this pressure-roller being such that the draw of said fabric isalways from the same center, regardless ot the amount accumulated onsaid reel.

In practice the warp-wires are carried from the spools XV around ingrooves in the rollers V V', then between the crosser-shafts R R', thenthrough the interstices e of the slat-carrier, then under thepressure-roller Z, and finally fastened to the reel Q. The number of thewarp-wires may be Varied at will, and the distance apart of these wiresis regulated by their position with relation to the grooves in therollers V V. By the rotation of the shafts R R the crosser-arms 9'thereon act against the wires in such a manner that while some areraised the remainder are lowered at regular intervals to form the shedfor a slat, the latter being placed in the receiver and carrier, asabove described. rlhe receiver and carrier being thrown forward by thecrankand-pitman mechanism above described, the slat is thus placed inthe shed formed by the action of the crossers against the warp-wires andforced between the grippers N, after which said receiver and carrierisreturned to its normal position. rlhe operation of weaving beingcontinued, the wires are drawn off their spools by the action of thecrossers, and as each slat is carried forward the fabric is forced ontoward the reel Q and the belt T is just tight enough on the pulleys I S.as to cause said reel to partially rotate whenever there is slack insaid fabric; otherwise this belt will slip on said pulleys.

In connection with the weaving mechanism above specified I may employ anautomatic slat-feed, the one preferred being illustrated by Figs. S to12,inclusive, and hereinafter described.

A feed-box A extends laterally from the upper side of the loom-frameadjacent to the opening g therein, and the outer end of this box issupported by a brace B', the latter being illustrated by full and dottedlines in Fig. 9. Extending up from the loom-frame parallel to theopening g therein is a wall C at a right angle to the rear wall of thefeed-box A', and guards D connect the wall C with' the front wall ofsaid feed-box, as best illustrated in Fig. S. The front wall of thefeedbox is provided with horizontal slots b and horizontal guides c',the latter being arranged in pairs adjacent to the slots. Looselyarranged between each pair of the guides is a sliding block d',detachably retained in its working position by means of a screw c',passed through the adjacent slot b', and a washer f, arranged on thescrew to bear against the inner side of the adjacent wall of thefeed-box. Each of the blocks CZ has a hinged section cl2, provided witha finger g', that extends through the adjacent slot b' in the feed-boxto bear against a bunch of slats arranged in said box to be successivelyfed to the reciprocating receiver and carrier above described, thisconstruction and arrangement of parts being clearly illustrated in Figs.S and l0. A flexible device 71. is made fast to the upper one of theblocks d and runs over a pulley t" on the lower guide for the same,thence down over another pulley j', mounted on the lower one of saidblocks, and then over still another pulley 7c', arranged on the lowerguide for the latter block to connect with the weight E', as illustratedin Fig. 10.

The upper end of the inner side C of the slat receiver and carrier isvertically extended, as best illustrated in Fig. 12, and provided withright-angled brackets m, to which I attach spring-fingers fn, the latterpassing the open inner end of the feed-box A as said slat receiver andcarrieris reciprocated and being of such length as to come inside theguards D', as best illustrated in Fig. 8.

In practice the sections (Z2 of the sliding blocks d are swung back. ontheir hinges to bring the fingers g out of the feed-box, a bunch ofslats placed in the latter, and said blocks run outward to raise theweight E', after which said hinged sections are swung back to bringtheir fingers in rear of said bunch of slats. The power of the weight Etends to run the blocks d forward toward the loom-frame, and thus theinnermost slat iu the feed-box is held against the guards D in the pathof the spring-fingers n on the extended upper end of the inner side ofthe IIO the bunch having been automatically fed to the receiver andcarrier, as above described, the descent of the weight E causes saidbunch f to move forward, and thus another slat is brought against theguards D', this operation being repeated as often as there are slatsremaining in the feed-box.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
